Simplifying
(x + 5)(x + 1) = x(x + 1)

Reorder the terms:
(5 + x)(x + 1) = x(x + 1)

Reorder the terms:
(5 + x)(1 + x) = x(x + 1)

Multiply (5 + x) * (1 + x)
(5(1 + x) + x(1 + x)) = x(x + 1)
((1 * 5 + x * 5) + x(1 + x)) = x(x + 1)
((5 + 5x) + x(1 + x)) = x(x + 1)
(5 + 5x + (1 * x + x * x)) = x(x + 1)
(5 + 5x + (1x + x2)) = x(x + 1)

Combine like terms: 5x + 1x = 6x
(5 + 6x + x2) = x(x + 1)

Reorder the terms:
5 + 6x + x2 = x(1 + x)
5 + 6x + x2 = (1 * x + x * x)
5 + 6x + x2 = (1x + x2)

Add '-1x2' to each side of the equation.
5 + 6x + x2 + -1x2 = 1x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
5 + 6x + 0 = 1x + x2 + -1x2
5 + 6x = 1x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
5 + 6x = 1x + 0
5 + 6x = 1x
